Abstract
A smoking article having reduced ignition propensity is disclosed. The smoking article includes a tobacco column, a wrapper surrounding the tobacco column and a filter element. The wrapper has a base permeability, an untreated area and a least one discrete area treated with a composition to reducing the base permeability. The discretely treated area interacts with a coal of a burning tobacco firecone as it advances to self-extinguish the smoking article. The composition of the treated area includes a permeability reducing substance, a burn rate retarding substance and a burn rate accelerating substance. Either the burn rate retarding substance or the burn rate accelerating substance acts as an organoleptic enhancing substance. In this way a smoker's experience when smoking either the at least one treated area or the untreated area is substantially the same.
